i don’t think everyone is bisexual, but i do believe that everyone is capable of being sexually attracted to both genders. But bisexuality means that u are able to also fall in love with, and grow with both genders. If you only feel sexually attracted to them, its not really bisexuality, its just lust.

No dear, everyone is not bisexual. However, everyone does have the choice to be bisexual.
I, for example, am not bisexual because I’m aromantic, meaning I don’t feel attraction towards anyone.
My friend, for another example, is not bisexual because she is gay and the thought of dating any man is disgusting to her (no she does not hate men, just hates the thought of dating them)

For one, it is impossible for someone to be bisexual because the TRUE/ORIGINAL definition of bisexual is “having the organs of both sexes in one being” (From Etymology Online). Therefore, its not the question of whether or not you are sexually attracted to both genders. Its the question of you having the sexual organs of both genders in one body. So saying that everyone is bisexual (understanding the original definition) is already a false statement because it is completely UNNATURAL for human beings.
